Description
Technical field
The invention belongs to new energy Battery case parts technical fields, are to be related to one kind for new energy more specifically
The explosion-proof vent valve of source battery cabinet.
Background technique
At present in industries such as new energy lithium battery, ternary batteries, in order to reach IP67 safety standard, new energy Battery case
It is required hermetically sealed, but new energy battery is in need in use is exhausted, in this way, if cabinet is completely enclosed, battery
The intracorporal pressure of the rear cabinet that works long hours can be excessive, there is the danger for generating explosion.To solve the above problems, new energy battery is raw
Producing producer can all select not only waterproof but also breathable explosion-proof vent valve to be mounted on cabinet.In this way, working as the intracorporal atmospheric pressure of case
After the certain numerical value of setting, overpressure gases will be discharged outside cabinet for explosion-proof vent valve, be kept in cabinet always in peace
Total pressure state.Explosion-proof vent valve in the prior art has the following disadvantages and defect: 1) due to explosion-proof vent valve individual difference,
The burst pressure that the ventilated membrane of each explosion-proof vent valve can bear is not quite similar, and the pressure that can be born is unadjustable;2) city
There is many ventilating grooves (hole) on used explosion-proof valve web plate on field, in transport or installation process, the object of some apicules is easy
Ventilated membrane is punctured across ventilating groove, explosion-proof vent valve is destroyed, this allows for not knowing when the installation of explosion-proof vent valve
Road ventilated membrane has been destroyed, and is existed using hidden danger;3) rear cover of existing explosion-proof vent valve can be easy to open, user
Member can arbitrarily carry out burst pressure adjusting, and there are security risks.
